DM114 Integrated Circuit Chip 8-Bit CONSTANT CURRENT LED DRIVERS with 3.3v ~ 5v supply voltage

DM114,DM115
8-Bit CONSTANT CURRENT LED DRIVERS with 3.3v ~ 5v Supply Voltage

General Description
The DM114,DM115 is the constant current driver specifically designed for LED display applications. The value of constant current can be varied using an external resistor. The devices include an 8-bit shift register, latches, and constant current drivers on a single Silicon CMOS chip.

Features
• Maximum Output Voltage: 17V
• Maximum Clock Frequency: 25MHz (Cascade Operation)
• Power Supply Voltage: 3.3V to 5.0V
• CMOS Compatible Input
• Package: PDIP16, SOP16, SSOP16
• Package and Pin Layout: Pin layout and functionality are similar to those of the ST2221A.
(Each characteristic value is different.)
